RTC DS3231 with AT24C32 eeprom incl. Battery

With this RTC (Real Time Clock) module it is very easy to keep track of the time. The communication goes through an I2C interface. This RTC module is based on the DS3231 in combination with a LIR2032 backup battery. You can also use the AT24C32 32K I2C EEPROM for additional storage. The difference with the DS1307 RTC module is that the DS3231 is more accurate due to the built-in crystal that is temperature compensated.

Package contents:

• 1x RTC DS3231 with AT24C32 eeprom
